Texas Instruments F28M36P63C2ZWTT

Overview

F28M36P63C2ZWTT from Texas Instruments is a dual-core Concerto™ microcontroller integrating an Arm® Cortex®-M3 (125 MHz) master subsystem and a TMS320C28x (150 MHz) real-time control subsystem on a single die. It features 1MB ECC flash, dual 12-bit ADCs (2.88 MSPS total), 12 ePWM modules with 16 high-resolution outputs, two D_CAN interfaces, 10/100 ENET 1588 MII, and USB OTG + PHY - deployed in industrial motor drives and solar inverters requiring synchronized communication and deterministic control.

For engineers reviewing the F28M36P63C2ZWTT datasheet, F28M36P63C2ZWTT pinout, F28M36P63C2ZWTT application, or F28M36P63C2ZWTT equivalent, this page delivers verified core frequencies, memory partitioning (shared RAM, IPC message RAM), analog subsystem specs (ADC channels, comparator+DAC units), safety features (ECC, dual security zones), and package-specific ball mapping for ZWT nFBGA - all confirmed against TI SPRS825F (Rev. F, June 2020).

Technical Context

The F28M36P63C2ZWTT implements tightly coupled interprocessor communication via 32 handshaking channels and dual 2KB IPC Message RAM blocks (parity-protected), enabling deterministic data exchange between Cortex-M3 and C28x subsystems without bus contention. Its clock architecture supports independent PLLs per subsystem, with dynamic ratio changes and strict integer divide constraints (e.g., 125 MHz M3 ↔ 125 MHz C28x or 75 MHz M3 ↔ 150 MHz C28x).

Real-time control is anchored by the C28x subsystem's Viterbi/Complex Math/CRC Unit (VCU), IEEE-754 FPU, and fault-tolerant peripherals including 12 ePWMs with trip-zone protection across 64 GPIO pins. The analog subsystem integrates two independent 12-bit ADCs (24 total channels, 347 ns conversion time) and six comparators each paired with a 10-bit DAC for fast-loop feedback in servo and inverter applications.

FAQ

What is the maximum operating frequency of each core in the F28M36P63C2ZWTT?

The F28M36P63C2ZWTT features an Arm Cortex-M3 core rated at 125 MHz and a TMS320C28x core rated at 150 MHz. However, due to shared clocking constraints, valid combinations include 125 MHz M3 + 125 MHz C28x or 75 MHz M3 + 150 MHz C28x - as specified in TI SPRS825F Table 3-2. These limits ensure stable operation and prevent timing violations between subsystems.

Does the F28M36P63C2ZWTT support hardware-based safety mechanisms for industrial certification?

Yes, the F28M36P63C2ZWTT includes multiple hardware safety features required for IEC 61508 SIL-2: ECC on flash and RAM, parity on non-ECC RAM, dual security zones with 128-bit passwords, NMI watchdogs per subsystem, critical register lock protection, and glitch-free GPIOs. These are documented in the Safety Manual (SPRUIK9) and enable systematic fault coverage in certified designs.

How many analog-to-digital converter channels does the F28M36P63C2ZWTT support, and what is their resolution?

The F28M36P63C2ZWTT integrates two independent 12-bit analog-to-digital converters (ADC1 and ADC2), each supporting 12 input channels for a total of 24 channels. Both ADCs operate at up to 2.88 MSPS aggregate sampling rate with 347 ns conversion time - confirmed in Section 5.10 of SPRS825F and validated for simultaneous sampling in motor current reconstruction.

What communication interfaces are available on the F28M36P63C2ZWTT for industrial networking?

The F28M36P63C2ZWTT provides 10/100 ENET with IEEE 1588 Precision Time Protocol (MII interface), USB OTG Full-Speed with integrated PHY, two D_CAN modules (pin-bootable), five UARTs, four SSI/SPI ports, two I²C interfaces, and a McBSP - enabling seamless integration into industrial Ethernet, fieldbus, and human-machine interface subsystems.

Is the F28M36P63C2ZWTT pin-compatible with other devices in the F28M36x family?

Yes, the F28M36P63C2ZWTT shares the same 289-ball ZWT nFBGA package and identical pinout with F28M36P53C2ZWTT, F28M36H53B2ZWTT, and F28M36H33B2ZWTT - as confirmed in TI's Mechanical, Packaging, and Orderable Information (Section 9). This allows direct PCB reuse across performance tiers within the Concerto family.
